Extensive interview process with tests w/ actual tests taken. The questions asked can sometimes be riddles, try to be confident. The actual written test I took had questions that were on par with some of the GMAT questions I was studying, a little intense and was strange because you didn't need any technical expertise to be an AE. Fun overall though, this company is an AMAZING opportunity for recent grads or someone looking to get their foot in the door in online marketing and/or lead gen.
